SMM Survey: Weekly Review of the Electrolyzer Industry, 2025-2024

Capacity side, the domestic alkaline electrolyzer market maintained 35.77GW this week, with no new capacity added. In terms of deliveries, as of April 24, 2025, Asens Hydrogen Energy delivered one 1,000 Nm³/H alkaline electrolyzer to Australia last week, while Xibei Hydrogen Energy delivered one 1,000 Nm³/H unit to a green hydrogen project in Jilin. For PEM, HydroVolta delivered one 50 Nm³/h unit to Europe last week. As of March 20, 2025, domestic companies (including overseas deliveries) have delivered a total of 10MW of alkaline electrolyzers (data sourced from public information).

Electrolyzer orders side, as of this week, the bid winner for the third batch of auxiliary equipment (hydrogen production system) procurement project of the 2x1,000MW ultra-supercritical unit project of Shaanxi Coal Xinyang was announced. The bid winner is Beijing Power Equipment Group, with the winning product being one 1,000 Nm³ alkaline electrolyzer. Additionally, LONGi Hydrogen recently signed a supply agreement with Saudi Arabia's NEOM for the world's largest single green hydrogen project, confirming at least one 2,000 Nm³ alkaline electrolyzer order. As of April 10, 2025, a total of at least 47 orders for 1,000 Nm³/H units and one 2,000 Nm³ alkaline electrolyzer have been confirmed, including 10 units for Xingong Green Hydrogen, 16 units for Sungrow Hydrogen, 12 units for CRRC Zhuzhou, 8 units for Sany Hydrogen, and 1 unit for Beijing Power Equipment Group.
